IMPROVEMENT IN BOOTS OR SHOES.

Speeieation forming part of Letters Patent No. 35,057, dated April 22,1362.

To all whom it may concern.-

Be it known that I, PIERRE BorssEr, of Paris, in the Empire of France,hayeinvented a new and useful Improvement in Boots or Shoes; and I dohereby declare that the following is a full and exact description of thesame, reference being,I had to the accompanying,` drawings, and to theletters of reference marked thereon.

Figure I represents a top view ot a shoe or boot sole, and Fig. II is asection of the same.

The nature of my invention. consists in the combination, with caoutchoucsoles for boots or shoes, of a metal piece or pieces pierced with asuitable thread-hole for the reception of screws by which theul'iper-leather and inner soles are seeurel y fastened to the caoutchoucsoles.

In the application. of india-rubber orguitapereha soles as a substitutefor leather soles to boots or shoes the greatest difficulty has existedheretofore in attachingI said soles irml y to the upper-leather orVamps. Screws have been used Ator this purpose, but trointhe nature ofthe caoutchouc itis'very diilicult to Amake the thread ot" the Screwshold firmly in this material, and after a very little use the screw willeasily pull out ol.' the same.

In the accompanyine` drawings, A relrn'esents the shank and heel ot asole made ol' caoutchouc, on. the forward end o'l which a leather sole,l, may be attached, or the whole sole may be made ol caoutchouc, itdesirable. (I represents the upper-leather or Vamps, which is turned in.between the outerorcaoutchoue sole, A, and the inner sole, l).

In the caoutchouc sole A small metal pieces uy are incorporated duringthe process ot' mal:- iup` said sole. These metal pieces o are providedwith a suitable hole in which a screw thread is eut corresponding withthe thread of the screws to be used.

The inner sole, D, and the upper-leather C are attached to thecaoutchouc sole A by nieans of any desired number of screws s, screwedthrough that part ot the caoutchouc situated above the metal pieces andthen into these metal pieces a, by which the screws will be preventedfrein pulling out, and which will hold the saine firm andvfast, similarto a nut.

Instead of small metal pieces being incorporated with the sole, as abovedescribed, a plate provided with the desired number of holes withscrew-threads cut in may be ineorpoi-ated therein 5 but I prefer the useof small pieces, as the weight is thereby not considerably increased.

I am aware that screws have been used before for the purpose attachingthe inner sole and upper-leather to the outer soles made of caoutchoucor its equivalent, said screws haying, been screwed into the sole, anddo therefore not claim the use of screws for the purpose ot' attachingthe upper-leather to caoutchouc soles; but

lYhat I claim as my invention, and desire to secure by .Letters Patent,is-

The combination, with a plate or nut, o, when the same embedded orincorporated within the .india-rubber or caoutchouc solo while beingmade, of a screw so arranged and operating` in connection with saidplate as to allow ot the sole beingr screwed up and fastened to theupper-leather, substantially in the manner and vfor the purposespeeiiied.
